Cocoa forControlEvents：WHATGOESHERE [英] Cocoa forControlEvents:WHATGOESHERE

问题描述

在Cocoa / Objective-C中，如果我以编程方式创建了一个按钮，那么我为我的控制事件输入什么？

In Cocoa/Objective-C if I have created a button programmatically, what do I put in for my control event?

[btnMakeChar addTarget:self action:@selector(makeChar:) forControlEvents:WHAT GOES HERE?];

在iOS中，您可以这样编写：forControlEvents：UIControlEventTouchUpInside

In iOS you can write it like so forControlEvents: UIControlEventTouchUpInside

我找不到任何东西，只显示可可，而不是可可。

I can't find anything to show what I would use for just cocoa, not cocoa touch

推荐答案

'm不确定我是否正确理解你，但如果你正在编程一个Mac，

I'm not sure if I understand you correctly, but if you're programming a Mac,

[theHappyButton setTarget:self];
[theHappyButton setAction:@selector(doStuff)];

它是两个单独的行，而不是iPhone上的一行代码。

it is two separate lines, rather than the one combined line of code on an iPhone.

我希望这是你之后的

在doco中找到它：在10.6 doco不是iOS），并搜索setAction：。你会在NSControl类参考中看到它。 NSButton当然是NSControl的子类。

To find it in the doco: choose on the 10.6 doco (not iOS) and search on "setAction:". You'll see it in NSControl Class Reference. NSButton is of course a subclass of NSControl.
